Half Life x Star Wars isn't a combination i saw being done often. Here's my Vortigaunt Jedi and two Sith hunters. Some info on the Jedi.
Terrafos
A Vintian Jedi Master, capeable of blending into any surrounding around him, no matter how unfitting it may seem. At an uncertain point in history, during one of his travels, Terrafos encountred a dimensional rift, that shifted his current trajectory to the border world of Xen, far from a galaxy he once knew. Forever stuck, he spent time in solitude, blending in with the border world, until one day...
Vortax
One of many Vortigaunt slaves working at a crystal mine, operating many machines. At a certain point during Nihilanth rule, Vortax linked his mind with a strange stone, that guided him into discovering a new Force, far beyond the reaches of Vortessence. This new found Force resulted in Vortax losing connection with his fellow Vorts, in turn, allowing him to slip away from Nihilanth's control, going into hiding with his master. Now following newly learnt traditions and fashioning his own blade of light, this Vortigaunt found a new path to freedom.
In Short: Vortigant who lost it to the pressures of slavery.
